You should understand that, on all contemporary Windows platforms, x86 (32-bit) application can be executed on WoW64, no matter what is the CPU
instruction-set architecture. Please see:

You should always know the CPU instruction-set architecture on the system you are working with. To learn the architecture used on Windows, go to Control Panel, System, Environment variables, see the variable PROCESSOR_ARCHITECTURE.
